REKONFIGURASI SISTEM PROTEKSI JARINGAN DISTRIBUSI PAINAN SETELAH PENAMBAHAN PLTM BAYANG NYALO
No full textPenambahan PLTM Bayang Nyalo pada jaringan distribusi Painan menyebabkan perubahan pada arus normal maksimum serta arus gangguan yang terdeteksi oleh relai proteksi. Kondisi ini dapat menyebabkan relai mengalami maloperasi atau gagal mendeteksi gangguan di area proteksinya. Oleh karena itu, diperlukan rekonfigurasi relai-relai. Tujuan penelitian ini, yaitu merekonfigurasi sistem proteksi jaringan distribusi Painan setelah penambahan PLTM Bayang Nyalo. Upaya perbaikan meliputi pemasangan relai arus lebih berarah di kedua pangkal feeder Painan, feeder dari PLTM Bayang Nyalo, konduktor penghubung rel di Gardu Hubung Pasar Baru, serta sisi LV dan HV setiap trafo di PLTM Bayang Nyalo untuk mengantisipasi arus gangguan yang berasal dari jaringan maupun PLTM Bayang Nyalo yang memiliki arah berbeda. Selain itu, dilakukan perubahan setting relai arus lebih di Feeder Salido, Feeder Lumpo, Feeder Bayang, dan Feeder Kapuah. Koordinasi relai yang telah direkonfigurasi dan disetting ini diuji menggunakan software DIgSILENT PowerFactory. Pengujian urutan kerja relai dilakukan dengan mensimulasikan pada berbagai titik gangguan, mencakup jenis gangguan seperti gangguan 3 fasa, 2 fasa, 2 fasa ke tanah, dan 1 fasa ke tanah. Rekonfigurasi sistem proteksi jaringan distribusi Painan setelah penambahan PLTM Bayang Nyalo telah berhasil didesain dengan menggunakan 12 relai arus lebih berarah dan 4 relai arus lebih. Setting relai pada sistem proteksi jaringan distribusi Painan setelah penambahan PLTM Bayang Nyalo telah dihitung dan diuji melalui simulasi proteksi pada DIgSILENT PowerFactory. Hasil simulasi menunjukkan bahwa relai-relai dapat berkoordinasi untuk 4 kondisi jaringan. Dimana grading margin terkecil yang ditemui adalah 0,521 detik
Using Instagram Reels as a Media for Government Public Service Information
No full textResearchers use the theory of new media characteristics proposed by Denis McQuail to reveal the reasons for using Instagram Reels by the Directorate General of Immigration as the main media in the publication of Letters of Support for Work and Holiday Visa (SDUWHV) services. The approach used is qualitative with descriptive methods. This research uses two data sources, namely primary and secondary. Primary data was obtained by interviewing sources, while secondary data was collected by library research and observing the Directorate General of Immigration's Instagram Reels social media. The research results show that the reasons for using Instagram Reels as SDUWHV information media are in line with Denis Mcquail's theory of new media characteristics, namely interactivity, social presence, media richness, autonomy, elements of playfulness, and privacy. The practical significance of this research lies in its ability to show how government agencies can use social media to increase public engagement in their programs. In addition, this research also provides insight into how government agencies can innovate their communication strategies to adapt to changes in media consumption behavior, especially among the younger generation who are active users of social media. Thus, this research is not only relevant for public and government communication practitioners but also for academics who are interested in understanding the dynamics of communication in the digital era and how government institutions can utilize new media for publication and educational purposes
